Question

5÷x=85÷1/9


2÷3=74÷x

5÷x=15÷24

Answer 1

Explicação passo-a-passo:

$\frac{5}{x} = 85 \div \frac{1}{9}$

$\frac{5}{x} = 85 \times \frac{9}{1}$

$\frac{5}{x} = 765$

5 = 765x

765x = 5

x = 5/765

x = 0,006

$\frac{2}{3} = \frac{74}{x}$

2x = 3 × 74

2x = 222

x = 222/2

x = 111

$\frac{5}{x} = \frac{15}{24}$

x × 15 = 24 × 5

15x = 120

x = 120/15

x = 8
